Some ActiveRecord extensions which are helpful for me in a couple of projects

active_record_extension.rb

module ActiveRecordExtension
  extend ActiveSupport::Concern

  module ClassMethods
    def from_current(period, options = { column: 'created_at' })
      raise "Invalid options in #{self.to_s}\##{__method__.to_s}" unless [:year, :quarter, :month, :week, :day].include? period

      start_method = "beginning_of_#{period.to_s}"
      end_method = "end_of_#{period.to_s}"

      where(options[:column].to_s => Date.today.send(start_method)..Date.today.send(end_method))
    end

    def between_dates(options = {})
      options = {
        from: Date.today.beginning_of_day,
        to: Date.today.end_of_day,
        column: 'created_at'
      }.merge options

      options[:from] = Date.parse(options[:from]) if options[:from].is_a? String
      options[:to] = Date.parse(options[:to]) if options[:to].is_a? String
      
      where(options[:column].to_s => options[:from]..options[:to])
    end
  end
end
